Dune Biodiversity of the Baja California Peninsula

Some of the longest stretches of undisturbed coast in North America are at risk of environmental degradation.

LepNet Digitization Project

Our Entomology Department is working on a multi-year project to digitize 150,000 specimens of Lepidoptera (butterflies and moths) from Southern California and Baja California, a known biodiversity hotspot. The important data associated with these specimens in our collection can be used to help inform important conservation activities. Learn more.
